Abstract (en)
[origin: WO2008008143A2] Methods and systems for transforming electric power between two or more portals. Any or all portals can be DC, single
phase AC, or multi-phase AC. Conversion is accomplished by a plurality of bi-directional conducting and blocking semiconductor switches which
alternately connect an inductor and parallel capacitor between said portals, such that energy is transferred into the inductor from one or more input
portals and/or phases, then the energy is transferred out of the inductor to one or more output portals and/or phases, with said parallel capacitor
facilitating "soft" turn-off, and with any excess inductor energy being returned back to the input Soft turn-on and reverse recovery is also facilitated.
Said bi-directional switches allow for two power transfers per inductor/capacitor cycle, thereby maximizing inductor/capacitor utilization as well as
providing for optimum converter operation with high input/output voltage ratios. Control means coordinate the switches to accomplish the desired
power transfers.
